Hyperwave API Functions

Integration with Apache

The integration with Apache and possible other servers has been
described in the separate chapter.

Classes

The API provided by the HW_API extension is fully object oriented.
It is very similar to the C++ interface of the Hyperwave SDK.
It consist of the following classes.

HW_API

HW_API_Object

HW_API_Attribute

HW_API_Error

HW_API_Content

HW_API_Reason

Some basic classes like HW_API_String,
HW_API_String_Array, etc., which exist in the
Hyperwave SDK have not been implemented since PHP has powerful
replacements for them.

Each class has certain method, whose names are identical to its
counterparts in the Hyperwave SDK. Passing arguments to this function
differs from all the other PHP extensions but is close to the C++ API of
the HW SDK. Instead of passing several parameters they are all put into
an associated array and passed as one parameter. The names of the keys
are identical to those documented in the HW SDK. The common parameters
are listed below. If other parameters are required they will be
documented if needed.

objectIdentifier The name or id of an object,
e.g. "rootcollection", "0x873A8768 0x00000002".

parentIdentifier The name or id of an object
which is considered to be a parent.

object An instance of class HW_API_Object.

parameters An instance of class HW_API_Object.

version The version of an object.

mode An integer value determine the way an
operation is executed.

attributeSelector Any array of strings, each
containing a name of an attribute. This is used if you retrieve the
object record and want to include certain attributes.

objectQuery A query to select certain object
out of a list of objects. This is used to reduce the number of objects
which was delivered by a function like
hw_api::children() or hw_api::find().
